Understand what is text mining and oracle text.

Text mining is the process of applying data mining techniques to text terms, also called text features or tokens. Text terms are words or groups of words that have been extracted from text documents and assigned numeric weights. Text terms are the fundamental unit of text that can be manipulated and analyzed.

Oracle Text is a Database technology that provides term extraction, word and theme searching, and other utilities for querying text. When columns of text are present in the training data, Oracle Data Mining uses Oracle Text utilities and term weighting strategies to transform the text for mining. Oracle Data Mining passes configuration information supplied by you to Oracle Text and uses the results in the model creation process.
